OnScreen WAS NOT intended to emulate the Windows keyboard
interface in its entirety. Although OnScreen appears to operate
just as the keyboard does, due to its design, certain applications
may not function properly with OnScreen. Special software
considerations have been made to make OnScreen as flexible as
possible, and the notes below offer information on configuration
settings that may make OnScreen work within your applications.
Also below is a complete discussion of settings, options, and
possible solutions to any incompatibilities.

OnScreen WAS intended to make certain operations easier because
the user can concentrate on the task at hand, not which input
device is required at the moment.

OnScreen allows the user to keep their eyes on the screen,
so the flow of work on a computer is uninterrupted. In essence,
OnScreen is just a standard Windows application that provides
special functionality.
